CELL-CASE.

Application filed. June 25, 1919.

To all whom it may concern lle it known that we, HERBERT T. CHERRY andJnrrns R. CARTER, citizens of the United States, both residing at Tama,in the county of Tania and State of Iowa, have invented certain new anduseful Improvements in Qell-Cases, of which the following is aspecification.

Cell cases comprising a plurality of intersecting and interlocking wallstrips forming individual cells are largely employed in shipping eggsand other goods. These cases are stacked one upon the other withinterposed flats in crates or boxes. The endsv of the strips aregenerally extended beyond the side walls of the case to form buffers forengagement with the walls of the crate or box to prevent damage to thegoods which may result from the cases shifting bodily in the crates orboxes. In practice the crates or boxes are often subjected to roughhandling and not only do the walls of the individual cells bend andbreak down but the buffers also bend and break, resulting in more orless damage to the eggs or other articles.

It is the object of our invention to reinforce and strengthen the wallsof the cells of a cell case and to more effectually provide against thecases shifting bodily in the crates or boxes.

And a further object of our invention is to provide a flat of novelconstruction with its edges strengthened by being crimped and adaptedfor use in connection with cell cases of standard construction withoutregard to the particular manner in which the wall strips of the caseareinterlocked.

In the drawings we have illustrated the invention in two of the forms inwhich it may be embodied and referring thereto Figure 1 is a perspectiveview of a portion of a cell case having our improved flat appliedthereto;

Fig. 2 is also a perspective view showing our improved flat providedwith parallel depressions extending in one direction;

Fig. 3 is a plan view showing another form of flat;

Fig. 4: is a sectional view on the line H of Fig. 3.

The cell case is provided with a plurality of intersecting strips 4, 5,which are interlocked in any suitable manner and have Specification ofLetters Patent.

their ends extended beyondthe outside walls of the case to form bufferst, 5. This is a well-known form of cell case and since our invention isnot limited to a cell case of any particular construction it will not benecessary to describe the manner in which the strips are interlocked. Aflat 6 of strawboard or other suitable material is arranged in the cellcase in the usual manner and the edges of the flat extend beyond theouter walls of the cell case to correspond with the buffers 5 so thatthe outer edges of the buffers and the outer edges of the flat will lieflush or substantially flush with each other to engage the walls of thecrate or box in which the cell case and flat are packed. Theseprojecting edges 6 of the flat constitute a border which is crimped toreinforce and strengthen them transversely to withstand end thrust orside thrust of the fiat in the crate or box.

The flat may be entirely plain between its crimped edges, as shown inFig. 1, or it may be provided with parallel depressions 7 extending inone direction and slitted at intervals at 8 to engage the strips of thecell case which these depressions cross, as shown in Fig. 2. Between thedepressions there are flat sections 9 which rest upon the other stripsof the cell case and upon the intersections of the strips to forinasubstantial support for the cell case resting upon the fiat as well as asubstantial area of engagement for the flat with the cell case uponwhich it rests.

In Figs. 3 and l we have shown a fiat provided with independent circulardepressions or indentations 10 to register with the cells of the case,those sections of the flat between the rows of depressions being plainto form flat surfaces for engagement with all of the wall strips of thecase, both those of the case upon which the flat rests as well as thoseof the cell case which rests thereon.

The crimped edges will materially strengthen the flat against bending orcollapsing under any tendency of the cell cases to shift bodily in thecrate or box and, furthermore, they will materially assist in preventingthe cell cases from shifting. As before stated, the cell cases arestacked one upon the other with interposed flats and since the flats arereinforced at their edges to prevent bending or collapsing they will notmove bodily in the crate or box and by frictional engagement with thecell cases they Will to a very material extent prevent the cell casesfrom shifting bodily and in like manner prevent the Walls of the cellsfrom bending or collapsing. In other Words, the rigidity of the flatafforded by the crimped edges Will be imparted to the Wall stripsforming the cell case by the frictional engagement of the fiat With thestrips of the cell case or cell cases and thereby add materially to therigidity of the cell case as a Whole. The depressions 7 or 10 in theflat add to the strength and rigidity of the fiat and to that extentmake the fiat stronger and more rigid although, as hereinbet'oreindicated, the crimped edges may be formed on a plain flat as well asupon fiats provided with depressions, as shown in the drawings.

And we do not Wish to be understood as confining the invention to aflat, plain or formed in any particular way between its crimped edges.And it may be also noted that While We prefer to crimp the four edges ofthe flat fairly satisfactory results may be obtained by crimpingopposite edges oi? the flat since in packing the crate or box such flatsmay be arranged to engage alternately the side Walls and the end Wallsof the crate or box.

We claim:

1. A fiat for a cell case consisting of a single sheet having a borderat its edges criinped transversely.

2. The combination of a cell case comprising a plurality of intersectingand interlocking Wall strips forming cells therebetween, and a flatarranged on said case and having a border at its edges projecting beyondthe outside Walls of the case and crimped transversely.

3. The combination of a cell case comprising a plurality of intersectingand interlocking Wall strips forming cells therebetween, the ends ofsaid strips projecting be yond the outside Walls of the case to formbuffers, and a flat consistingof a single sheet arranged on said caseand having a border at its edges projecting beyond the outside Walls ofthe case to correspond with the proj ecting buffers and crimpedtransversely.

' a. The combination of a cell case eo1n prising a plurality ofintersecting and interlocking Wall strips forming cells therebetween,and a fiat arranged on said case and projecting beyond the outside Wallsthereof,

said flat having parallel depressions With transverse slits therein toengage opposite Wall strips of said cells and having its edges crimpedtransversely thereof.
